The phosphide ion is stable
Phosphorus forms a -3 ion called phosphide.
P3- This is the phosphide ion, but it is not stable in water, only with 3H in PH3 (comparable with ammonia NH3) or with some metal ions (eg. Li3P, Ca3P2, AlP) it is found as pure substance. There are also other form with negatively charged phosphorous in it.
Nitride Ion.
The ion of phosphorous (P) is P^3- and is referred to as phosphide.
The charge on the phosphide ion in zinc phosphide is -3, because phosphorus typically forms a -3 charge when it becomes an anion.
When phosphorus forms an ion, it typically gains three electrons to achieve a full outer electron shell. This results in the formation of the phosphide ion, which has a 3- charge. This allows phosphorus to attain a stable electron configuration similar to a noble gas.
The most stable monatomic ion formed from phosphorus is the phosphide ion (P3-), where phosphorus gains three electrons to achieve a full octet, similar to the noble gas configuration of argon.
Most probably 10 electrons as a phosphide ion with 3-charge has 8 valence electrons.
When phosphorus forms an ion, it typically gains three electrons to achieve a stable electron configuration. This results in the formation of a phosphide ion with a 3- charge.
Yes, ammonium phosphide is an ionic compound. It is formed from the ionic bonding between the ammonium ion (NH4+) and the phosphide ion (P3-).
Phosphide, like every element, ultimately has the goal of having eight electrons in its outermost shell (satisfying the octet rule). To satisfy its octet, phosphide gains three electrons, which makes it more negative. Therefore, a phosphide ion's charge is -3.
When phosphorus achieves a noble gas configuration, it gains three electrons to become the phosphide ion (P³⁻). This allows it to achieve the stable electron configuration of a noble gas, similar to argon.
